Answer:
It is 3/-3
Step-by-step explanation:
I put those ordered pairs in a chart
1 2
-2 5
Then I saw how many numbers it took to get two from five, which is 3. I also took how many numbers it would take to get from one to negative two, which is -3. I turned it i to slope form, y over x, and got 3/-3.
The slope of the line with this 2 points (1,2) and (-2,5) is -1
Solution:
Need to determine slope of the line passing through points (1,2) and (-2,5)
For a line passing through [tex]\left(x_{1}, y_{1}\right),\left(x_{2}, y_{2}\right)[/tex] , Slope of line "m" is given as,
[tex]m=\frac{\left(y_{2}-y_{1}\right)}{\left(x_{2}-x_{1}\right)}[/tex]
[tex]\text { In our case } x_{1}=1, y_{1}=2, x_{2}=-2, y_{2}=5[/tex]
Substituting given value in "m" we get:
[tex]m=\frac{(5-2)}{(-2-1)}=-\frac{3}{3}=-1[/tex]
Hence slope of the line passing through (1,2) and (-2,5) is -1
